We have completely revised our bulk import and export files to make all the new features available via bulk import. Furthermore, we have significantly improved the clarity and usability of the file. It is now organized  around campaign type and ad format with refined help texts. Also, the import file now includes two additional tabs: "Portfolio list" (list of available portfolios with IDs) and "Assets list" (contains available assets per campaign type separated by logo, custom image, and video) to better support you with the mapping when creating and updating campaigns via bulk import.
